Our results of evaluation
Global climate is changing rapidly compared to the pace of
natural variations in climate that have occurred throughout Earth’s history.
Global average temperature has increased by about 1.8°F from 1901 to 2016, and
observational evidence does not support any credible natural explanations for
this amount of warming; instead, the evidence consistently points to human
activities, especially emissions of greenhouse or heat-trapping gases, as the
dominant cause.
Global average sea level has risen by about 7–8 inches
(about 16–21 cm) since 1900, with almost half this rise occurring since 1993 as
oceans have warmed and land-based ice has melted. Relative to the year 2000,
sea level is very likely to rise 1 to 4 feet (0.3 to 1.3 m) by the end of the
century. Emerging science regarding Antarctic ice sheet stability suggests
that, for higher scenarios, a rise exceeding 8 feet (2.4 m) by 2100 is
physically possible, although the probability of such an extreme outcome cannot
currently be assessed.
In the Arctic, annual average temperatures have increased
more than twice as fast as the global average, accompanied by thawing
permafrost and loss of sea ice and glacier mass. Arctic-wide glacial and sea
ice loss is expected to continue; by mid-century, it is very likely that the
Arctic will be nearly free of sea ice in late summer. Permafrost is expected to
continue to thaw over the coming century as well, and the carbon dioxide and
methane released from thawing permafrost has the potential to amplify
human-induced warming, possibly significantly.
Global average sea level has risen by about 7–8 inches
(16–21 cm) since 1900, with almost half this rise occurring since 1993 as
oceans have warmed and land-based ice has melted (very high confidence).
Relative to the year 2000, sea level is very likely to rise 1 to 4 feet (0.3 to
1.3 m) by the end of the century (medium confidence). Emerging science
regarding Antarctic ice sheet stability suggests that, for higher scenarios, a
rise exceeding 8 feet (2.4 m) by 2100 is physically possible, although the probability
of such an extreme outcome cannot currently be assessed.
The climate change resulting from human-caused emissions of
carbon dioxide will persist for decades to millennia. Self-reinforcing cycles
within the climate system have the potential to accelerate human-induced change
and even shift Earth’s climate system into new states that are very different
from those experienced in the recent past. Future changes outside the range
projected by climate models cannot be ruled out (very high confidence), and due
to their systematic tendency to underestimate temperature change during past
warm periods, models.
